Briefly, it was to provide a machine embodying novel features for makingand inserting metallic fasteners in the soles of shoes and the like,comprising a wire feeding mechanism, a plunger fastener insertingmechanism, and a knife or wire shearing mechanism, the latter adapted toform the respective fasteners and successively position each fastener asformed in the path of the plunger mechanism for inserting said fastenerin the material to be united, said mechanisms being synchronouslyassociated, a control rod mechanism for moving said plunger in insertingdirection, and means associated with said control rod forV preventingits upward movement until the plunger has completed its downward stroke,so that a respective fastener is formed, positioned screw I2, adaptedto`adjustably clamp the lower end I3, of thesubstantially horn-shaped anvilwith respect to said plunger, and inserted in theV materials to beunited during each downward strokeofgsaid plunger mechanism, that wedesigned thev device forming the subject matter of this invention.'

vIn the illustrated embodiment characterizing this invention there isshown a frame, A, comprising a pedestal section I, and a top section 2.The pedestal section lis formed with an integral base portion 3, andY inthe present instance tapers towards its upperv end terminating in alateral flange 4. Said frame section is of hollow construction and isformed in its `respective sides with elongated openings 5, and formedintegral withV or suitably connected to flange V4, isatableor shelfsection 6, on which is mounted frame section 2 bolted orotherwisefsuitably secured thereto. Section 2 is formed with asubstantially rectangular base l, which at its free end is formed with avertical bearing opening 8, in which is mounted movable bushing element9, terminating at its upper end in split ring I0, and through themeetingends of which is mounted adjusting member Ill, formed on itsupper end with anvil or material contacting face I5, which is inVerticalalignment with lower endV I3. Anvil member I4 is adjustable inaccordance with the dif- Vferent shapes-and types of shoes or materialbeing operated upon,fasrwill be apparent.

Section 2 at one Vend of base 1, is formed Wit Y vertical standard I6,terminating at its upper end 1in head Il, extending in verticalalignment with The face of head "I'I is formed at opposite edgeswithflange projections- I8, on which is mounted face plate I9, secured tosaid head by set screws 29,' or other suitable fastening 'means VTheplate I9, is suitably recessed as at -2I, to provide a seat for plunger22, slidably mounted therein. The extremity of plunger 22,

is countersunk rto rreceive a cam block 23, secured Y by set screw 2liand dowel pins 25, said block exmtends beyond one edge of the plunger,and is vformed 'at its lowerfedge with cam face 26. The plunger point2l, is formed with head 28, adapted to seat in the complementalcountersunk openings formed in saidplunger and cam plate as will beclear Without further discussion.V

22 and edge 33, as at 3l and formed with an opening 32. The upper en dof said plate I9 is recessed as at 33 in which is mounted hold-backratchetlike nger 34, formed on one side with wire engaging-tooth 35 andon the opposite side with apertured extensionr 36, adaptedtoreceivedowel pin 3l carried by said plate I9. Mounted intermediate the lowerend of'elernent 34 and the wall of said recess isspring 38 forholding-tooth 35 in "engagement'with' wire 39 to prevent slippage orwithdrawal of the wire, unless moved out of engagement therewith, by themanual movement of end r4i), as will be clear without furtherexplanation.V Y Y Y VThe wire feeding mechanism C, is adapted to bemounted in the recess or countersunk portion V3i, and 'comprises' block42',formed with flange 43, extending the length of the block at oneedge,

, Yand ange portionlill at the lower opposite cor- Iextension 4Brotatably mounted on theY suitably `ner adapted to form a seat forspring 45 engaging the lower end of ratchet finger 46 formed, similar tothe finger 3d, on one side with wire engaging tooth lli and ontheropposite side with securedpin, 49. v'Mounted on the rear surface ofPlate I9,is countersunk intermediate'plungerr 51 and is adapted to beforced down by cam 53 and tooth B'I in engagement with wire 39 forcesthe wire downward a distanceequalto the limit of movement of saidmechanism C, as and for a purpose, Vhereinafter more fully appearing.

Mounted at the lower end of recess 3i, Vplate 59 is secured by fasteningelement 60and is formed adjacent its upper inner cornerV with Vslot BIadapted to register with the diagonal tube 62 formed in plate I9 andconstitutes a guide for wire 39 as it is` advanced by feedingmechanismVV C to the wire cutting knife or shearing assembly D-now to bedescribedi` The lower vend'of plate I9 is formed with a Vshapedextension 33, on which is Vmounted a similarly shaped stationaryknife or blade element 34, suitably'secured thereto by screws 35. Theface of said element 3G is thicker at its upper edge than at its loweredge andis formed with a'curved inclined slotV -69 and with a diagonalslot 56 'slightly enlarged at its upper end as at GS and with itsV lowerend'terrninating at Vsaid curved seat.` The edge 6l of said slotconstitutes the cutting or shearing edge of said stationary element Sli,which is also formed with asimilar shaped perpendicular slot 38 adaptedto receive the plunger point 2T, as vwill hereinafter more fully appear.Y

The complemental movable wire cuttingror f l shearing-blade 69 ismovably mounted on plate `lili constructed with an outwardly andupwardlyV extending arm 19, formed at its upper edge with a rearwardlyextending projection ii terminating in an inclined contact face l2, andthe end of said arm being inclined to form cam Contact surface 'I3 forengagement withV cam surface 26 of plunger block 23. Said arm I9 isformed atV its upper inner edge with plunger contact extension 1rdadapted to reduce the frictional engagement of the plunger with said armduring its recprocas torymovement, as willrhereinafter moreY fullyappear.

through aperture YIii of stationary plate 34, and through the lower endof extension t3V to which it is rigidly secured by pin TI. Said pin 'I5isY Movable blade 69 is apertured at'itsv ylower end to receive pin "i5,adapted to extend formed with opening I8 extending in alignment withslot 68 formed in stationary blade '64.

Movable blade 69 is formed on Vits rear face,

with curved surface 69' oppositely inclined to the complemental seatVB4' rof Yblade Sli which Vit is adapted to engage, and the lower endfQof said blade below surface 69 isthicker than the portion above saidsurface. Y in said rear surface with a slot i9V which enters surface 69'and continues through said thickened portion 69'l as anopening extendingto the lower edge of said blade YYas will be apparent. Said slot 'I9 isslightly enlarged at its upper endas at 80 similar to slots 66 and68,and the edge 8i thereof constitutes the cutting or shearing edge Vofsaid blade in conjunction with edge El of stationary blade S4 when saidelements are operatively as.

sembled. The upper end of slot 'I9 isadapted to initially register withslot orY guide 62 so as to Said blade 69 is formed receive .the wire 39when it is advanced therein by feeding mechanism C a distancecorresponding to the length of the fastener 82. Fastener 82 is formed asblade 69 is moved to bring slot 'ig into registration with slot 68,which movement of said blade positions the fastener to be acted on byplunger point 2l, as will be apparent as the description proceeds.

f In this connection it will be observed that in forming the fasteningelement 82, the shearing movement of the cutting edges of Hifi and 69cuts or shears the wire at an angle and thereby forms fastener 32 withan oppositely inclined edge 83, at each end which is advantageous ineifecting proper clinching of the element in the layers of material E aswillV be hereinafter more fully described.

Plate i9 is recessed as at Sil to accommodate arm i3 of movable knife 69and the hook-like member 85 pivotallymounted as at le and formed withelongated finger portion 'i adapted to en-A gage face 'i2 and maintainknife Se in wire receiving position, and downward movement of cam block23 is adapted to move arm 'iii to a perpendicular position aligning slotopening 'i9 with slot 68, and the upward movement of cam 23 engagingunder the substantially right angularly extending trigger portion S8causes finger 8l to return arm 7B to its initial position.

Cam 53 extends through .slot E3 in i? and is formed with arm 89 normallyresting in a substantially upright position, the upper curved endV ofwhich is adapted to be engaged by the lower end 98 of arm di integrallyconnected with head F intermediate its length. Slightly spaced from arm9| is operating rod 92 having its upper end suitably connected to head Fadjacent one end thereof, A threaded bifurcated member 93 is mounted onthe other end of head F by pin gli and the upper end cf plunger 22 isformed with an end member 55 suitably connected thereto, said end memberbeing formed with threads extending oppositely to the threads of member93, to which it is detachably connected by nut Q.

l Plunger 22, arm 9i and control pedal rod Q2, ex-

tend through suitable openings in top plate 9'! secured to head |`l bythreaded bolt Q8, said plate 91 being also recessed to permit end i8 ofwire holder 34 to extend therethrough, so that the same may bedisengagedV from wire 39 as desired.

In order to limit the movement of cam 53 when returned to initialposition by spring 5?, a pin 99 is suitably mounted in block 55, and inorder that said cam may be moved beyond pin out of engagement with wirefeeding mechanism C, thereby rendering said mechanism inactive, whenrepairing or adjusting the machine as desired, a pin led is mountedadjacent the upper end of said camV to form a hand grip therefore.

Pedal rod 92 extends through bearing opening lill in head i'i and asimilar opening ||l| in basel t and thro-ugh section 6 and terminates inbifurcated member m2 threadedly or otherwise suitably mounted thereon;Member |62 is connected to pedal arm E83 by pin or bolt |04, one end ofsaid pedal arm i @3 being pivotally mounted on pin |65 in ears ietsuitably formed on base 3. Said arm extends through slots |85 formed inbase l and has mounted on its free end pedal li'i secured thereto in anysuitable manner. One end of spring |38 is connected to anchor clip |63mounted on rod 92 and secured adjacent clip |82 by nut H6. The other endof said spring is connected to hook l i suitably connected `to flange 4,and is adapted to exert an upward pull on control or pedal rod 32 tonormally maintain said rod and pedal |01 in elevated position. It isevident that when |01 is depressed, rod 92, head F, plunger 22 and arm9| will be impelled downwardly, and in order that said plunger may notreturn to its initial raised position until it has reached the limit ofits downward stroke, a ratchet mechanism G is associated with rod 92,and which mechanism will now be described.

Mechanism C- comprising a plate H2 secured by screws, or any suitablemanner to standard 2, and mounted on said plate substantially central ofits length secured thereto by a screw or in any suitable manner is aslotted anchor post i3. Ratchet arm lill is mounted in said slotted postsubstantially central of its length as at H, and is slightly arcuate inconfiguration with its upper end rounded as at HS and its lower endformed with a face il of ratchet linger H8 and heel |59. Mounted o-nsaid rod 92 is a cam member 29 suitably secured thereto by set screwEEE, and series of ratchet teeth |22 are formed in the rod adjacent saidcam, and adapted to be engaged by nger H8 of arm H4. Said cam i2@ isadapted to engage end l I6 when it reaches the limit of its upwardstroke, causing finger H8 to engage the lowermost ratchet tooth |22. Aspring |23 is mounted on plate H2 secured by plate E24 and screw |25,and is formed on its free end vwith a lateral catch |25 adapted toengage heel H8 and maintain finger H8 in engagement with ratchet teeth|22 during the downward stroke of rod Q2, as clearly shown in Fig. 13 cithe drawings. When rod 92 reaches the limit of its downward stroke cam429 engages finger M8 kicking it back and causing catch IZt of spring|23 to engage face if?, and maintaining said iinger out of the path ofteeth E22, as clearly shown in Fig. 14, until rod 92 returns to itsinitial position and cam i2@ again engages surface E causing nger i8 toagain engage the lowermost tooth |22 as in the irst instance. While wehave shown one form of spring for controlling arm i ifi, it is obviousthat this arrangement may be varied without departing from the scope orspirit o-f the invention.

in order to limit the upward movement of pedal lD' and rod 92, a bracketstop member |21 secured by a suitable fastening element is mounted onthe inner surface of section i, adapted to be engaged by buifer or shockabsorbing medium E28 constructed of rubber or the like suitably mountedin the end of holder |29 mounted on and secured to pedal arm |03,similar to element |1132, and which not only insures a gage for theupward stroke of rod 92, but constitutes a buifer for reducing the shockand vibration incident to the release of pedal |01.

In order that the anvil section l5 may move upwardly and engage theunder surface of the shoe sole or other material being united and holdthe same in iirin position with respect to opening i9 simultaneouslywith the downward movement of pedal arm |33, a rod |30 suitablyconnected at its lower end to arm |93 by bifurcated member to2', similarto arm 92, extends upwardly through a slot in the rear wall of standardwith its upper end suitably connected to one end of spring |3|, theother end of said spring being connected to hook |32 suitably connectedto one end of arm |33. Arm |33 is fulcrumed on pin i3d mounted inbracket |35 suitably secured to frame section by a bolt or in anysuitable manner, and rotatably Vmounted on pin |36 in the end of armA|33 is roller |31 adapted to engage the end of bushing 9 and elevateanvil member when pedal |91 is depressed as will be clear withoutfurther discussion. Spring |3|V 5 is adapted to compensate for differentthicknesses of material E, as will be well understood.

Mounted on the upper end of section 2 by bolts |38 is 'a bracket |39 inthe upper end of which is mounted casing |69, in which is rotatablymount- 10v ed reel |9| on which is wound wire 39 adapted to Ybe heldinplace by nut |42. Wire 39 extends throughv opening |93, through top 91,between the wall of recess 33 and tooth 35, through'feeding mechanism Cbetween fiange 43 and tooth t1, Y and through guide 62 vto knife 69.Tooth 91 being normally in engagement Ywith wire 39, each downwardstroke of mechanism C advances said wire into knife 69 a predetermineddistance, and

in order to vary the distance the wire is advanced at veach stroke,thereby varying the length of the fastening elements formed by knifemechanism D, it is necessary to control mechanism C accordingly.Therefore, as the bottom wall of opening 32 constitutes a stop for thedownward movement or stroke of mechanism C, to vary `the feeding strokeof said mechanism, it is necessary tocontrol and vary the stop Vforlimiting the upward movement of said mechanism C when same is returnedto its uppermost position by 3()` `spring 51, and which is accomplishedby the 'structure now to be described.

Mounted Yadjacent ledge 52 in block 50 and projecting laterallytherefrom is pin |99 adapted to extend through slot |95 formed in flange16 35 and adapted to engage lug |136 integrally formed with or securedto lever |41, suitably journaled at its lower end on stub shaftV |418,integrally Vformed'with Yor suitably mounted in the edge of plate i9 towhich it is secured by nut |99. Le-

40 ver |131 is formed at its upper end with operating handle |56 andwith tooth |5| for engage- Y ment with the teeth of curved rack |52suitably mounted on plate 9 adjacent its upper edge. It is apparent thatmovement of' lever v|91 and stop lug |46 adapted to engage pin Miti,determines. the upward movement of feeding mechanism C, and therefore, apredetermined setting of lever M1 controls the length of the feedingstroke of said mechanism C and determines the length of the fasteningelements 82,

as desired.

In order to regulate the position of the shoe or layers'of `material tobe united with respect to the fastener or nail feeding opening 19 andplunger point 21 operating therethrough so as toY insure `a uniform lineof Stitching with respect to the edge of such material, a gage orregulating mechanism H is mounted adjacent the lower edge of knifemechanism D, which Y, will now b-e described.

Mechanism H comprisesV a bracket |53 suitablyformed with or connected tostandard |6 formed at its free end with a Vertical stub shaft |53 and ananchor slide plate'l55 constructed Vwith an extension |56 suitablyformed at its outer curved edge with rack teethr |51, and projecting atan angle rearwardly with its end spaced from said rack is a projection|158 rotatably mounted on said stub shaft |54 and secured inanydesiredadjusted position by thumb screw |59. Extension |56 isV formedsubstantially central of its length with a stub shaft |66, on which isrotatably mounted lever |6| substantially central of its length. ThefreeV end ofV said lever constitutes an operating handle and the otherendV is rounded or ball' pointedfor engagement in thetransversesubstantially V-shaped slot |62 formed in the upper surface of slide |63slidably mounted in recess |64 formed in saidr plate adjacent one edge,said'sli'de be-Y 5. ing formed with a depending projection |65V adaptedto limit the retractile ,movement of said slide, the opposite movementbeing limited by lug |66 suitably formed on extension |56 constituting astop for lever 16|. Lever |6| adje-*l0 I cent its free end is alsoformed with operating knob |61. It is apparent that the edge of thematerial to be united `when placed intermediate anvil l5' and knifemechanism -D will contact Y the end of'sli-de |63, which constitutes agage V15 or guide settable as desired, to control the points ofinsertion of the fasteners with respect to the edge of the sole ormaterials beingfunited. Y

`In order to properly house the parts mountedf in plate |9,'a detachablecover plate |68 is pro- 2Q 7 vided suitably secured by bolts |69 and,wing nuts |16. c

Operation Although theoperation of theY device Vwuld 251V Y seem to beclear from the above description, it Y might be well to further statethat when theV wire has been introduced into the machine passed beyondYfinger 33, through mechanism C andV guide 62 with its end adjacent theupperY edge 30 1 ofknife 69 and in alignment withA opening 19; lever |91having been set according to the length of fastener desired, and gageYmechanism H properly set, and the material to be united positioned onanvil face I5 with its edge in engage- 35 ment with slideV |63, downwardmovement of pedal |91 will pull down rod 92,;head E', armV 9| andplunger 22. Duringthe downward stroke of said plunger 22 arm 9| engagescam 53 VIVnQV.-

ing feeding mechanism C, and tooth i1 in engage- 40 v t ment withwire 39feeds said wire into the complemental slots 66 and 19, a distance equalto the downward stroke of mechanism C. When said mechanism has reachedthe limit of its downward stroke, the surf-ace 26 of cam 23 en-V 45gages cam surface 23 of arm 10, moving said arm to perpendicularpositionand actuating said knife 69, whereby the cutting edges 61 ofthestationary knife and 8| of themovable knife effect shearing of wire 39vand forming fastener 56 element 82, with an Yinclined point, and as arm16 reaches itsv limit of movement, opening 19 carrying the fastener 82will register with op'en-V Y ing 53 and in'alignrnent withplunger'point` 21` by which time the plunger point has reached the 55upper edge of said knife mechanism H, and as it continues on itsdownward stroke itexpels fastener 82 from opening 19 and' inserts it inthe layers of material tovbeV united.V The lowerV end of the fastenercontacting anvil l5 is clinched 69 Y vany upward movement of said rod,plunger and associated parts until all such mechanisms have reached thelimit of their downward strokes;V and as saidr rod 92 reaches such'limitcam |20 with spring |23 effects movement of ratchet Varm 75 lili toinoperative position, thereby permitting said rod to be returned to itsinitial position. It. will be observed that the action of all of theabove. parts takes place during the downward vmovement of plunger 22,and While it is travelling. from its initial position tothe limit of itsdownward movement.V Upon removalof pressure from pedal till', spring IBSreturns said pedal, pedal rod, and plunger to their initial positionsand, ready. for another cycle of operation, as will be clear withoutfurther description.

It will also be noted that the return stroke -or upward movement ofplunger 22 causes cam Z3 to engage and elevate trigger 88 causing finger8.1 to move arm 'lll to return knife element 69 to its initial positionwith opening 19 in alignment with guide 62 in readiness to receive theend of wire 39, asin the first instance.

From the above it is apparent that we; have designed a machine formaking and inserting metallic fasteners: in shoe soles and the like,com- Vpact in form, embodying novel mechanisms coactingtosever the wire,position the fastener with respect to the inserting mechanism andinsertV the same in the materials to be united, during the downwardstroke of the plunger mechanism, yet manufacturable at a minimum costand efcient for the purposes intended. Y

Although in practice we have found that the fcrnrof our inventionillustrated the accompanying drawings and referred to in the abovedescription as the preferred embodiment, is the most efficient andpractical, yet realizing that conditions concurrent with the adoption ofour invention will necessarily vary, we desire to emphasize that variousminor changes in details of construction, proportion and arrangements ofparts, may be resorted to within the scope of the appended claimswithout departing from or sacrii'lcing any of the principles of thisinvention.
